DNA Traces Back to Adam and Eve

"Adam named his wife Eve, because she would become the mother of all the living." (Genesis 3:20)
DNA Traces Back to Adam and Eve

To identify a common ancestor whose genetics have been passed down, we must look for traits that are inherited from generation to generation with minimal or no alteration. One such trait is the mitochondrial DNA passed down from mother to both daughters and sons, and the Y chromosome passed down from father to only sons.

In 1987, a group of population geneticists published a study in the journal Nature which revealed the existence of a common ancestor, known as "Mitochondrial Eve." They analyzed the mitochondrial DNA of 147 individuals from different ethnic groups and concluded that all humans can trace their ancestry back to one woman. Professor Karl Skorecki, a DNA expert and discoverer of the "Cohen Gene," confirms this by stating that:
“Analysis of mitochondrial DNA of all contemporary humans sampled today indicates that all of the different variations in the sequence of mitochondrial DNA (mtDNA) trace back, or converge to an original sequence in a given woman.”
Similarly, research on Y chromosomes confirmed the existence of "Y-Chromosomal Adam," the common ancestor of all living men.

Thus, while Y-Chromosomal Adam is the ancestor of every living man, Mitochondrial Eve is the mother of all living humans, male and female! This is beautifully consistent with the biblical account of human history.

In addition, unlike nuclear DNA, mitochondrial DNA has only 16,569 base pairs (DNA’s building blocks) as opposed to over 6 billion base pairs in our nucleus. So mutations are much easier to track. (In fact, the highest number of mutations recorded in the human race is just over 120.) What does this mean? Such a limited number of mutations means that little time has passed for mutations to occur since the first mother passed down her DNA! These results make sense if today’s billions of people are the descendants of only eight people on Noah’s Ark who lived approximately 6,000 years ago according to biblical chronology. However, if there was more time, like the hundreds of thousands of years that the evolutionists claim (in addition to the millions of years since humans evolved from an ape-like ancestor), we would expect to find far more DNA differences. But we don’t.

Two recent major studies of modern humans’ Y chromosomes also suggest that ‘Y-chromosome Adam’ and ‘mitochondrial Eve’ may have lived around the same time after all.2,3 Once again consistent with the biblical account.

The dates assigned to mitochondrial Eve (tens to hundreds of thousands of years) by evolutionists don't match the biblical chronology, however, this is because they are are based upon ‘molecular clock’ assumptions, which were calibrated by evolutionary beliefs about when certain evolutionary events occurred, supposedly millions of years ago. The aforementioned mutation rates directly ‘challenge’ the evolutionary long-age claim, and indicate that mitochondrial Eve lived around 6,000 to 6,500 years ago, right in the ballpark for the true ‘mother of all living’ (Genesis 3:20).

What we can say with fair certainty is that, regardless of time frames and alleged contemporaries, every man alive today descended from one man while every human alive today descended from one woman. Moreover, you cannot say that science doesn't confirm the Bible. Because it does.
